Distribution: N - Frl (Tretiach & Hafellner 2000), TAA (Dalla Torre & Sarnthein 1902), Lomb (Ravera & al. 2017, Gheza 2018, 2019), Piem (S-F69694), Lig.
Description: Primary thallus squamulose, the squamules persistent, prominent, stiff, elongate-crenate, up to 5 mm long, 0.5-3.5 mm wide, grey-green to bronze-green above, white and corticate beneath, forming dense, often convex, up to 10 cm wide (usually smaller) cushions. Podetia rather rare, small, 0.3-0.8(-1) cm tall, 1-3 mm thick, greenish brown to yellowish brown, irregularly cylindrical to clavate, cupless, continuously corticate, sometimes with small cracks, often squamulose at the base. Apothecia normally present when podetia are well-developed, brown, convex, usually forming aggregates. Asci 8-spored, clavate, thickened at apex, with a K/I+ blue tholus and a K/I+ strongly blue outer gelatinous sheath, Cladonia-type. Ascospores 1-celled, hyaline, ellipsoid. Pycnidia brown, semi-immersed in the basal squamules, with a colourless jelly. Conidia bacilliform. Photobiont chlorococcoid. Spot tests: K-, KC-, C+ bright emerald green, P+ yellow, UV+ whitish. Chemistry: baeomycesic and squamatic acids, strepsilin, sometimes traces of barbatic and 4-O-demethylbarbatic acids.
Note: a boreal-montane to tropical lichen found on humous soil overlaying siliceous rocks and amongst bryophytes in humid depressions periodically filled by water, in open situations; probably restricted to the Alps in Italy.
Growth form: Fruticose

Substrata: soil, terricolous mosses, and plant debris
Photobiont: green algae other than Trentepohlia

Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
